Applications of a Microfluidic Amplifier As a Bi-Stable Device in an Oxygen Delivery System

Abstract

This paper presents the application of a planar, fluid amplifier which has been used as a bi-stable element in an intermittent, oxygen delivery device. The proportional fluid amplifier is made bi-stable by positive feedback: by connecting its outputs to its inputs, through a fluid resistor network. The fluidic fluid amplifier is the device that gave birth to the fluidics technology, in 1959, at the former Harry Diamond Laboratories (U.S. Army).
